MORF4L2 induces immunosuppressive microenvironment and immunotherapy resistance through GRHL2/MORF4L2/H4K12Ac/CSF1 axis in triple-negative breast cancer.

Background: Although immunotherapy has achieved great progress in advanced triple-negative breast cancer (TNBC), there are still numerous patients who do not benefit from immunotherapy. Therefore, identification of the key molecule that induces immune escape and clarification of its specific mechanism in TNBC are urgently needed.

Methods: In this research, single cell sequencing and bulk sequencing were conducted for biomarker screening.

Targeting BRIX1 via Engineered Exosomes Induces Nucleolar Stress to Suppress Cancer Progression.

Elevated ribosome biogenesis correlates with the rapid growth and progression of cancer. Targeted blockade of ribosome biogenesis induces nucleolar stress, which preferentially leads to the elimination of malignant cells. In this study, it is reported that the nucleolar protein BRIX1 is a critical regulator for the homeostasis between ribosome biogenesis and p53 activation.

A strategy to reconstitute immunity without GVHD via adoptive allogeneic Tscm therapy.

Introduction: Adoption of allogeneic T cells directly supplements the number of T cells and rapidly induces T-cell immunity, which has good efficacy for treating some tumors and immunodeficiency diseases. However, poor adoptive T-cell engraftment and graft-versus-host disease (GVHD) limit the application of these methods. Alloreactive T-cell clones were eliminated from the donor T-cell repertoire, and the remaining T-cell clones were prepared as Tscm for T-cell adoptive treatment to reconstruct recipient T-cell immunity without GVHD.

Metabolomics Identifies a Panel of Diagnostic Biomarkers for Early Human Embryonic Development Arrest.

Early embryonic development arrest (EEDA) is a unique form of early spontaneous abortion in pregnant women, which is previously suggested to be associated with metabolic abnormalities. Noninvasive biomarkers would significantly improve its diagnosis and clinical outcome. Here, we performed a targeted metabolomics study in plasma from EEDA patients ( = 27) and normal pregnant women (NPW, = 27) using liquid chromatography coupled with mass spectrometry (LC-MS) to identify potential diagnostic marker metabolites.

Bushen Jieyu Tiaochong Formula reduces apoptosis of granulosa cells via the PERK-ATF4-CHOP signaling pathway in a rat model of polycystic ovary syndrome with chronic stress.

Ethnopharmacological Relevance: Polycystic ovary syndrome (PCOS) is a common and complex endocrine disorder that is also an important cause of infertility. Adverse psychological stress can aggravate the occurrence and development of PCOS. Bushen Jieyu Tiaochong Formula (BJTF), a prescription of Traditional Chinese Medicine (TCM), has been used in the treatment of PCOS and shown to be effective in reducing negative emotion.

[Observation on therapeutic effect of polycystic ovary syndrome of damp-phlegm constitution treated with embedding therapy on back-shu points and front-mu points combined with needle-pricking therapy on Sifeng (EX-UE 10)].

Objective: To investigate the effectiveness of polycystic ovary syndrome (PCOS) of damp-phlegm constitution treated with embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10).

Methods: Eighty-five patients were randomly divided into 2 groups of observation group (42 cases) and control group (43 cases). Embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10) were applied to the observation group.
